Specification of Letters Patent.

Patented Marchfi, 1906.

Application filed April 17. 1905. Seria No. 255,928.

. Be it known that I,'FRANK K. SINGER, a citizen of the United States, and a resident of Wheeling, in the county of Ohio and State of West Virginia, have made certain new and useful Improvements in Lightning'Arresters, of which the following is a specification.

My invention is an improvement in li htning-arresters, being especially designs to provide a' lightning-protector for telephonecables, &c. and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is'a sectional elevation of an apparatus embodying my invention, and Fig. 2 is a detail longitudmal section of the fuse detached. Fig. 3 is a detail cross-section onabout line 3 3 of Fig. 1.

In the construction shown I provide a frame havin a metal bar or strap 16, bent at its lower en formin the base portion 16. To the u per end of t e frame 16 is secured atrA the liard-rubber block B, the frame 16 extending along the inner side of the block near its lower end, while along the opposite side of the block extends the downwardlye prpf'ecting wing C of the German-silver fuse an carbon ho ding plate C, whose to Win extends across the upper end of the b ock and over to and connects with the upper end of the fuse, as shown in Fig. 1.

' cop er washer- D. r of t e plate C extends below the blockB and In securing the plate 0 to the blockB, I em ploy a screw D', which may be a brass machine terminal screw and is rovided with the hexagonal nuts D, D, an I) and with the The depending wing G alongside a line carbon block E, which fits against a plate E, of mica. one thirty-sec- 0nd of an inch thick and which. se arates it from a carbon 'groundlate E orming a sparkap, as shown in ig. 1'.

s own in Fi 1, an insulatin strip or block 23 is secured by a flat-head rass machine-screw 17 to the base 16" of the frame, a nut 18 and copperwasher 19 being provided on the screw 17 abovethe block 23 and a hexagonal brass block 26 being interposedbetween the insulating-block 23 and the base 16:I 'as'shown'in Fig. 1. A brass terminal an lower end, fits from below in an opening in the insulating-block 23 and receives above the said block a brass hexagonal block 20,

fuse-socket 22, having a head 22 atits socket in place. This socket 22 has a threaded socket 22 in its upper end, in which screws the threaded tenon at the lower end of the fuse-tube, as presently described. A cable connection 21 1s soldered'in connection with the socket-block 22 at 25 and this connection 21, which may be a German-silver s ring, fits at 21 in a nick in the insulatin b ock 23 and being soldered at 25 to the bloc 22 operates to prevent the block 22 from turning, and it also serves to hold the cable connection 21 from getting loose or out of place. plotyed for securing the base 16 in place he fuse-tube is provided at its lower end with a brass terminal 38, having a depending threaded tenon which screws into the socket 22 of' the brass terminal 22, and at the upper end of the tube I rovide a hexa onal nut 32, which binds the erman-silver se-holder O or 6 against a metal cap 33 at the upper end of the fiber tube 37, to which cap 33 the upper end of the choke-coil 35 is soldered, such choke-coil being disposed around the upper end of'thefuse-tube 37 and being soldered at its lower end at 4 to the three-ampere ribbon fuse 30, which is disposed within the fuse-tube 37 and extends down therein to the brass terminal 22, as shown in Fig. 1. The choke-coil 35 comprises about twenty turns ofNo. 22

A flat-head iron screw 24. maybe emtriple-covered wire, shellac-varnished, and

the fuse-tube 37 is a fiber tube, shellacvar-- nished. The tube 37 is secured by a fiat-head brass machine-screw 36 to the terminal 38, a

soldered connection 39 being effected between the lower end of the fuse 3,0 and the terminal i 38, as will be understood from Fig. 1 of' the drawin s.

It wiIl be noticed that the circuit in Fig. 1 is from the line to the choke-coil, through the choke-coil and three-ampere fuse to the cable.

In Fig. 1 I show a construction of the parts forming the spark-gap, in which the sparkap occurs at the lower end of the block B, a fine carbon block E, mica plate E, and groundplate E being provided, ,as before described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is l 1. The combination substantially as herein described of the fuse-holding tube,the fuse within the tube, the choke-coil outside the' tube, suitable terminals, and a spark-gap device in connection therewith.

2. In an apparatus, scribed, the combination of aframe, a non- IIO substantially as detubular casing extending between said lineconducting block supported thereon and havin g a fuse-holding line-plate and spark-'gap devices cooperating therewith, a fuse-holding tube connected at-one end with the said lineplate, a terminal block having a plate for connection with the cable, and connected with the other end of the fuse-tube, a fuse-strip in the said tube and a choke-coil wound about the tube and in electrical connection at one end with the line-plate and at its other end with the fuse, substantially as set forth.

3. The combination with the frame having an upright and a base portion, a non-conducting block on the base portion, a terminal block supported b the non-conducting block and having a plate for cable connection, a non-conducting block supported on the upright of the frame, a line-connection plate, a screw securing said plate to the block, sparkgap devices in connection with said plate, a
